RESEARCH SCENARIO 2

A private all-girls elementary school has developed two different uniform designs: Design A and Design B. They are hoping at least one of the designs will be preferred by both mothers and fathers. Analyze the data to determine if there is a relationship between uniform design and parent.

Hypotheses

H0(Null Hypotheses): There is no assication between parents and uniform design. H1(Alternate Hypotheses): There is an assocation between parents and uniform design.

Result

A Chi-Square Test of Independence was conducted to examine the association between parents (father, mother) and uniform design preference (Design A, Design B) among 100 participants. There was no statistical association between parent type and uniform design preference, χ²(1, N = 100) = 3.24, p = .07, The effect size was small (Cramér’s V = 0.18).
